Just trying the understand this all and what is the best system to go with. I have and ego and 3 of them basically, 3 batteries so I guess that's the core of the mechanism.
I have 4 of the mega carts and I'm just reading that the tank mechanism is the way to go? I'm just not sure what I actually need. If anyone would provide some links, that would be cool.
There ain't no such thing as a best system. It isn't there. This technology is quite a way from being perfected. All systems have their good and bad points. Furthermore the way you use it will be unique to you. You have to find what works best for you. Your choices with an eGo are:
Mega Cartos - you have them and don't like them.
Regular 510 Cartos - Boge or Ikenvape are the big names here. Will have to be refilled more often than the megas but, a lot people like them. You can carry several, switch them out and refill later, if you wish.
Atomizers and cartridges - As far as I'm concerned these leak so much that I think those that use them like to absorb nic through their skin.
Direct Dripping - Read up on it. You drip on the atomizer every few hits.
Tanks - A and B now. You'll have to get a tank atomizer that and some tanks. If you want A tanks, you need an A atomizer. If you want B tanks, you have to use a B atomizer. The Bs are bigger and hold more. Other than that, I'm not sure there's a lot of difference. Mixed reviews.
Oher Stuff - Things like smartcarts, map tanks, heaven knows what else. Some people love them for a while but, there are lots of complaints long term.
Basically anything for a 510 or eGo will work on your eGo batteries. However, you have to find what works best for you. We can't tell you for sure what that will be.
